In cases like this I like having a different constructor for each case:
b1 = Buffer.new(1024)
b2 = Buffer.fromString("hello world")
b3 = Buffer.fromBuffer(b2, 14)
One advantage of separating the functions is that if you have a type
error in your code and pass the wrong value to the constructor you get
an error immediately instead of the program silently doing the wrong
thing.
